This species’ geographic range extends from southeast Venezuela to French Guiana, Amazon basin in Brazil, Colombia, Ecuador, Peru, and Bolivia. In Venezuela, it has been reported from the States of Bolívar (Reserva Forestal Imataca, and km13 on the road from El Dorado to Santa Elena de Uairén), and Amazonas (base of Cerro de la Neblina, and Mavaca river). Its altitudinal range is 0-500m asl.
Habitat and Ecology
This is an arboreal species living in pristine tropical rainforests, usually found on trees around temporary and semi-temporary pools during the wet season. A specimen from the Gran Sabana region of Venezuela was found calling from a Heliconia leaf near the edge of a temporary pond in the forest after a rain. It lays eggs on leaves and tadpoles develop in pools. At Santa Cecilia, Ecuador, individuals were found at night on bushes and low trees in forest (Duellman, 1978). At Yasuní National Park, Ecuador, specimens have been collected in open areas and floodable forests on shrubs and aquatic edges (Ron, 2001).
It is generally uncommon (common in Suriname).
Various forms of habitat loss no doubt impact local populations, but overall, this species is not significantly threatened.
Several populations are found within protected areas. In Ecuador, its geographic range overlaps with Reserva de Producción de Faunística Cuyabeno, Reserva Biológica Limoncocha, and Parque Nacional Yasuní. The population from Reserva Forestal Imataca in Venezuela has a high risk of becoming endangered once the forest is subject of logging practices and consequent depauperation of the original pristine forest vegetation.
